Description

The present invention relates to a fan assembly and a method of generating a display that presents an index of air quality.

Traditional household fans typically include a set of blades or vanes mounted to rotate about an axis, and a drive that rotates a set of blades to generate airflow. The motion and circulation of the air flow results in "wind chill" or breeze, and as a result the user experiences a cooling effect as heat is dissipated by convection and evaporation. Generally, the blades are generally located inside the cage, which allows airflow to pass through the housing while preventing the user from contacting the rotating blades when using the fan.

U.S. Pat. No. 2,488,467 describes a fan that does not use a blade housed in a cage to expel air from the fan assembly. Instead, the fan assembly comprises a base that houses a motor-driven impeller to draw in air, and a set of concentric annular nozzles connected to this base, each of which is located in front of the nozzle. It is equipped with an annular outlet that is designed to release airflow from the fan. Each nozzle extends around a bore axis that defines the bore around which this nozzle extends.

Each nozzle is in the shape of an airfoil, so the airfoil has a leading edge located at the rear of the nozzle, a trailing edge located at the front of the nozzle, and an airfoil extending between the leading and trailing edges. Can be considered to have. In US Pat. No. 2,488,467, the chord line of each nozzle is parallel to the bore axis of the nozzle. The air outlet is located on the chord line and is arranged so as to discharge the air flow along the chord line in the direction away from the nozzle.

Other fan assemblies that do not use blades housed in cages to expel air from the fan assembly are described in WO 2010/100451. This fan assembly comprises a cylindrical base containing a motor-driven impeller for drawing main airflow into it, and a single annular nozzle connected to this base with an annular opening / outlet for main air. The flow is discharged from the fan through the annular opening / exit. The nozzle defines an opening, and air in the local environment of the fan assembly is drawn through this opening by the main airflow discharged from the annular opening, amplifying the main airflow. The nozzles include the Coanda surface and the openings are located on the Coanda surface to direct the main air flow. The Coanda surface extends symmetrically around the central axis of the opening, and the airflow generated from the fan assembly is in the form of a cylindrical or truncated cone-shaped annular jet.

International Publication No. 2010/046691 also describes the fan assembly. The fan assembly comprises a cylindrical base containing a motor driven impeller for drawing main airflow into it, and an annular nozzle connected to this base with an annular air outlet, the main airflow from the fan. It is discharged through the annular air outlet. The fan assembly comprises a filter for removing particulate matter from the air flow. The filter can be provided upstream of the motor driven impeller, in which the particulate matter is removed from the air stream before passing through the impeller. This protects the impeller from debris and dust that can be sucked into the fan assembly and damage it. Alternatively, the filter can be provided on the downstream side of the motor-driven impeller. In this configuration, air containing any exhaust material drawn through a motor driven impeller can be filtered and cleaned before it travels through the components of the fan assembly and is fed to the user.

International Publication No. 2016/128732 describes fan assemblies similar to International Publication No. 2010/100451 and International Publication No. 2010/046691. The fan assembly includes air inlets that extend around the entire perimeter of the fan body to maximize the area available for air drawn into the fan assembly. Thus, the fan assembly is equipped with a tubular barrel filter and a nozzle detachably attached to the body, which fits concentrically on the fan body and fits across the fan body upstream of the air inlet. Surround the circumference. The filter does not couple to either the body or the nozzle, but is firmly secured in place by the nozzle when attached to the body and can only be removed from the fan assembly after the nozzle has been removed. This configuration allows the filter to simply drop onto the body before it is firmly seated in place by the engagement of the nozzle with the body, and the filter is to allow cleaning or replacement. It can be easily removed from the main body after removing the nozzle.

The fan assemblies described in International Publication No. 2010/100451, International Publication No. 2010/046691 and International Publication No. 2016/128732 each have a plurality of user-operable buttons on which the user can operate the fan. To prepare for. Also, International Publication No. 2012/017219 describes a fan assembly in the form of a portable fan heater, which allows a user to control multiple functions of the fan assembly. It is equipped with a user-operable button and a display device that gives the user a visual instruction of the temperature set value of the fan assembly. Similarly, US Pat. The solid is explained. Specifically, the number of current speed settings for the fan assembly is displayed on the display device. In both International Publication No. 2012/017219 and British Patent No. 2509111, the display device is in the form of a double / double digit 7 element LED display device.

Includes an upper curved portion 1303 and a lower curved portion 1304 joining the lower ends of two relatively linear portions 1301 and 1302.

Thus, the nozzle 1300 is concentric with the elongated annular inner casing portion 1370 and includes an elongated annular outer casing portion 1360 extending around the elongated annular inner casing portion 1370. In this embodiment, the inner casing portion 1370 and the outer casing portion 1360 are separate components. However, they can be integrally formed as a single component. Further, the nozzle 1300 has a curved rear casing portion 1380 forming the rear portion of the nozzle 1300, and the inner end of the curved rear casing portion 1380 is connected to the rear end of the inner casing portion 1370. In this embodiment, the inner casing portion 1370 and the curved rear casing portion 1380 are separate components connected to each other using, for example, screws and / or adhesives. However, they can also be integrally formed as a single component. The curved rear casing portion 1380 has a substantially elongated annular cross section perpendicular to the central axis (X) of the inner bore 1500 of the nozzle 1300 and a substantially semicircular cross section parallel to the central axis (X) of the inner bore 1500 of the nozzle 1300.

The rear portion 1371 is angled outward from the rear end of the inner casing 1370 away from the central axis (X) of the inner bore 1500. Further, the front side portion 1372 is angled outward from the rear end of the inner casing 1370 away from the central axis (X) of the inner bore 1500, but the angle is larger than the angle of the rear side portion 1371. Therefore, the front side portion 1372 of the inner casing portion 1370 is tapered towards the front end of the outer casing 1360, but does not meet the front end of the outer casing portion 1360, and the front end of the inner casing portion 1370 and the outer casing portion 1360. The space between the front end defines the slot forming the first air outlet 1310 of the nozzle 1300.

Next, the outer casing portion 1360 extends from the front portion of the nozzle 1300 toward the curved rear casing portion 1380, but does not meet the curved rear casing portion 1380 and is curved with the rear end of the outer casing portion 1360. The space between the rear casing portion 1380 and the rear end of the rear casing portion 1380 defines a slot forming the second air outlet 1320 of the nozzle 1300.

Therefore, the outer casing portion 1360, the inner casing portion 1370, and the curved rear casing portion 1380 carry air from the air inlet 1340 of the nozzle 1300 to one or both of the first air outlet 1310 and the second air outlet 1380. Define an internal passage to do so. In other words, the inner passage 1330 is bounded by the inner surfaces of the outer casing portion 1360, the inner casing portion 1370, and the curved rear casing portion 1380. The internal passage 1330 has two air flows in which air entering the nozzle 1300 through the air inlet 1340 enters the lower curved portion 1304 of the nozzle 1300 and each flows into one of the linear portions 1301 and 1302 of the nozzle 1300.

Nozzle 1300 has an outer casing portion 1360 and an inner casing portion 1370 at the top curved portion 1303 and the bottom curved portion 1304 of the nozzle 1300, respectively, so that air does not leak substantially from the curved portion of the internal passage 1330 of the nozzle 1300. It further includes two curved sealing members 1365 for forming a seal between them. Thus, the nozzle 1300 includes two elongated first air outlets 1310a, 1310b, each located on each elongated side of the central bore 1500.

Therefore, the valve members 1410a and 1410b are each configured to move in a direction substantially parallel to the central axis (X) of the bore / opening 1500. Therefore, the valve 1400 is configured such that the rotation of the rack 1440 is converted into the movement of the valve members 1410a, 1410b in a direction substantially parallel to the central axis (X) of the bore / opening 1500.

The arcuate racks shown in FIGS. 10 and 11 to translate the rotation of the rack 1440 into the movement of the valve members 1410a, 1410b in a direction substantially parallel to the central axis (X) of the bore / opening 1500. The 1440 comprises a pair of surfaces 1441a, 1441b projecting from the rack 1440 in a direction substantially parallel to the central axis (X) of the bore / opening 1500, each of these projecting surfaces 1441a, 1441b being an arcuate rack. Curved to follow the curvature of the 1440, the rack 1440 is configured such that a pair of faces 1441a, 1441b are located on either side of the pinion 1431 when the pinion 1431 is engaged with the rack 1440. Next, each of these protruding surfaces 1441a, 1441b extends across the curved surface at an angle of about 45 ° with respect to the rotation axis of the rack 1440, and the follower pins 1411a project from the corresponding valve members 1410a, 1410b. , A linear cam in the form of cam slots 1442a, 1442b configured to be engaged by 1411b, the cam slots 1442a, 1442b provided on both protruding surfaces are angled in the same direction.

In addition, the first valve actuator 1450a of the pair of valve actuators is rotatably connected / attached to the first end of the arcuate rack 1440, and the second valve actuator 1450b of the pair of valve actuators It is rotatably connected / attached to the opposite second end of the arcuate rack 1440. The valve actuators 1450a, 1450b are elongated (arranged so as to extend along the elongated side portions 1301 and 1302 of the internal passage 1330), and the upper cam slot 1451 and the valve actuator provided toward the upper ends of the valve actuators 1450a, 1450b. A lower cam slot 1452 provided toward the lower ends of the 1450a and 1450b is provided. The upper cam slot 1451 and the lower cam slot 1452 extend across the corresponding valve actuators 1450a, 1450b at an angle of about 45 ° with respect to the central axis (X) of the bore 15000, respectively. It is configured to be engaged by follower pins 1412, 1413 protruding from the members 1410a, 1410b. The cam slots 1451a, 1452a on the first valve actuator 1450a of the valve actuator are angled upward as the cam slot extends from the rear to the front of the valve actuator 1450a, but the second valve actuator of the valve actuator. The cam slots 1451b, 1452b on the 1450b are angled downward as the cam slot extends from the rear to the front of the valve actuator 1450b.

In particular, the rotation of the arcuate rack 1440 causes the protruding surfaces 1441a and 1441b to rotate in the same direction. In this regard, if the cam slots 1442a, 1442b provided on the surfaces 1441a, 1441b protruding from the rack 1440 are angled in the same direction, the rotation of the curved surfaces 1441a, 1441b in the same direction will be the first. It is converted into a horizontal motion in the same direction of the valve member 1410a of 1 and the second 1410b.

In addition, the rotation of the arcuate rack 1440 causes vertical displacements of the first and second ends of the arcuate rack 1440, followed by the first and second ends of the arcuate rack 1440. The vertical displacement of the above causes the valves actuators 1450a and 1450b rotatably connected to the end of the rack 1440 to be displaced in the vertical direction. In particular, the rotation of the arcuate rack 1440 causes an upward movement of the first and second ends of the arcuate rack 1440 and one of the connected valve actuators 1450a, 1450b, which causes the arcuate rack 1440 to move upward. It causes a downward movement of the first and second ends, as well as the other of the connected valve actuators 1450a, 1450b. The vertical displacement of the valve actuators 1450a, 1450b causes the angled cam slots 1451, 1452 provided on the valve actuators 1450a, 1450b to move relative to the cam followers 1412, 1413 of the corresponding valve members 1410a, 1410b, respectively. The angles of the cam slots 1451 and 1452 convert the vertical displacement of the valve actuators 1450a and 1450b into the horizontal movement of the valve members 1410a and 1410b in a direction parallel to the central axis (X) of the bore 15000. In this regard, if the cam slots 1451a, 1452b provided on the first valve actuator 1450a are angled in the opposite direction to the cam slots provided on the second valve actuator 1450b, the first The vertical displacement of the valve actuator 1450a and the second valve actuator 1450b in the opposite direction is converted into horizontal movement of the first valve member 1410a and the second 1410b in the same direction.

Since it is substantially closed, the entire main air flow is directed toward the first air outlets 1310a and 1310b. When both the valve members 1410a and 1410b provided in the internal passage 1330 are at the second end position, the elongated portion of the substantially J-shaped cross-sectional portion of the valve members 1410a and 1410b is the corresponding heater assembly 1390a and 1390b. It will come into contact with the inner circumference / edge of the frame 1392. Therefore, the valve members 1410a, 1410b substantially close the inlet from the rest of the internal passage 1330 into the first airflow channels 1312a, 1312b, thus making the entire main airflow a second airflow outlet 1320. Will be directed to. If both the valve members 1410a, 1410b are located between the first and second end positions, then both the first airflow channels 1312a, 13120b and the second airflow channel 1320 are internal passages. It will be open to the rest of the 1330, the first part of the main airflow will be directed to the first air outlets 1310a, 1310b and the second part of the main airflow will be the second airflow.

Secondary airflow is generated by the entrainment of air from the external environment, especially from the area around the nozzle 1300. The secondary airflow combines with the main airflow discharged from the first air outlets 1310a, 1310b to produce a combined amplified airflow discharged forward from the nozzle 1300. In contrast, the fact that the main airflow is emitted from the second air outlet 1320 such that the main airflow radiates / opens substantially away from the fan assembly 1000 means that this airflow is in the fan assembly 1000. Prevents air from being drawn in from the outside through the opening / bore 1500 configured by the nozzle 1300, thereby creating a non-amplified air flow.
